SC16IS750 SPI-UART bridge that is more complicated to deal with than simple UART communication, but allows for a much higher baud rate if one wants to communicate with the WiFly at higher-than-115200 baud speeds.
My question is about “much higher baud rate”.
Will I be able to connect to WiFly from Arduino via UART with 250000 baud rate? Or it will still require SPI?
